I'm not familiar with PDP gear, but if the outputs are just 5-24vdc, I
wouldn't worry too much. I might still check them with a volt meter, just
to make sure. For any high voltage outputs, 100V+, I would put a jumper
clip lead across them if they have large filter caps, and they are not
connected to anything that could draw them down. Large hv caps have been
known to build up a charge on their own, given enough time. I would think
that Digital would have put bleeder resistors across any such caps and
outputs, but you never know...

If ya do jumper any outputs, make sure you put a tag on the equipment as a
reminder of the jumpers...you don't want to fry anything when it gets
powered up ;)
